Reviews of Rutland Products 600 Castable Refractory Cement - 12.5 Lb (Pack of

Customer Ratings:

Product pretty much worked as advertised. My goal was to replace a cracked refractory vertical wall casting for an existing built-in fireplace. Created wood forms, sealed them with two coats of polyurethane, used caster oil as a mold release and cast the parts. I kept the part covered with a damp towel to ensure a proper cure and waited a week before removing the part. My mold had screw-on side pieces, so after removing them, I had no trouble releasing the rest of the part. If there was a negative, my finished casting has small air pockets on the finish-side, which I filled using a slurry mix of Rutland cement, rubbing it into the open pores.....seemed to work okay. To drive off any residual water after from the casting, I baked the thing in my home oven set at first 220 F, then after an hour, cranked it up to 400F for an hour. I've had a fire in the fireplace and all seems to be okay.

I used this product to pour my own replacement back firebrick in an obsolete fireplace. The cement was easy to work with. Just made a form, cut some wire mesh to bind the cement together and poured. I know it is cement, but the cast seems "rock solid'. I heated the cast in the oven for about 2 hours up to 450f. I have burned 2 smaller fires in the fireplace so far as it is not all that cold yet. I gave a 4 star rating because I have not been able to get some roaring fires going to really put the cement to the test. by the way, I used 2 12.5 lb tubs to cast 18"x20"x1.5".

It did super after the company told me the right stuff. You would think that would be easy, but it was not.

This cement was very easy to use, the container size makes it very convenient to mix up just the right amount in a five gallon bucket. Consistency can be varied from a fairly stiff putty to a smoother flowing slurry. I repaired the cracks and spaces in a prefab fireplace built in the mid 70's. I haven't used the fireplace yet, so I'm reserving a star untill I see how the repairs hold up.

One note of caution: This and most cements/concretes contain ingredients that will dry out bare skin! Use gloves if your skin is on the sensitive side.
